If the sequence of letters is A, F, K, P, ___, what comes next?

- DW
Solution & Step-by-step Explanation
Let us look at the positional values of the given letters in the English alphabet:
A=1
F=6
K=11
P=16
Now, let us find the common difference between consecutive terms:
6−1=5
11−6=5
16−11=5
The pattern is a constant addition of +5 to the positional value of the preceding letter.
Following this rule, the next positional value will be:
16+5=21
The letter corresponding to the alphabetical position 21 is U.
A=1
F=6
K=11
P=16
Now, let us find the common difference between consecutive terms:
6−1=5
11−6=5
16−11=5
The pattern is a constant addition of +5 to the positional value of the preceding letter.
Following this rule, the next positional value will be:
16+5=21
The letter corresponding to the alphabetical position 21 is U.
